Abstract (en)
[origin: WO2007078223A1] A proposed spread spectrum signal receiver includes a radio signal processing unit, which is at least partly implemented in software running on a processor. The processing unit is adapted to determine a candidate collection of subsets of signal sources among a group of potential signal sources (S1 -S9). Each member of the collection is a subset of the group of potential signal sources, which is defined by a criterion that an anticipated processing intensity required to derive the position/time related data from that subset is equal to or less than a maximum specified processing intensity. Each subset also contains at least a minimum number of signal sources necessary to produce the position/time related data. The processing unit is further adapted to select a set of preferred signal sources based on a candidate subset, which is associated with a highest estimated quality of the position/time related data attainable during a subsequent operating period for the receiver without exceeding the maximum specified processing intensity. Then, during the subsequent operating period, the receiver receives spread spectrum signals from the selected set of signal sources, and based on the received signals produces position/time related data.
